A polythematic imitative fantasia in mode of 85 compases. It is built of straightforward imitative procedures throughout.
I – Themes 1 & 2 voice pairs A/S --> T/B (1st note vary a little) then 3 is tacked on and imitated to complete section at 24.
II – Theme 4 long in Seminima movement accompanied by Semibreve s above in one voice only. 5 follows immediately. Similar theme type, but canonically imitated to 59.
III – Theme 6 motivic cadential formula imitated ad nauseam to final K at 85.

Venegas de Henestrosa reworked this fantasia. See 1557/2, no. 71 [Anglés edition, p. 105-6, Fantasia XVII]
